Axios unexpected End of File when accessing https://mas.to

[MarkMcKinney]

Hey team,

Whenever I try to access https://mas.to via getInstance() or registerApp() I receive the following error:

Any idea why? I've tested https://mastodon.social and https://botsin.space with no problems. When I go to that endpoint directly, there seems to be a correct output.

May have to do with the URL validation? Mas.to is a pretty odd URL with the ending and overall shortness. Just my initial two cents.

[h3poteto]

I got it. The cause is : axios/axios#5346

[MarkMcKinney]

That fix worked, thank you!
